Abstract

filme reciclável para termoformação. trata-se de filmes recicláveis que têm pelo menos uma primeira camada que contém um polietileno de alta densidade e um agente nucleante, uma segunda camada que contém um polietileno de alta densidade e uma terceira camada que contém um polietileno de alta densidade e um agente nucleante que pode ser usado para termoformar componentes de embalagem. a estrutura de filme é vantajosa, visto que pode ser mais facilmente termoformada do que filmes de polietileno de alta densidade tradicionais e pode manter o formato assumido durante a termoformação, exibindo deformação ou encolhimento mínimo.recyclable film for thermoforming. These are recyclable films that have at least a first layer that contains a high-density polyethylene and a nucleating agent, a second layer that contains a high-density polyethylene and a third layer that contains a high-density polyethylene and a nucleating agent. which can be used to thermoform packaging components. The film structure is advantageous in that it can be more easily thermoformed than traditional high-density polyethylene films and can maintain the assumed shape during thermoforming, exhibiting minimal warping or shrinkage.
